All Time SAP PP Interview Questions
1. Can we create Production order without bom and routing ?
yes we can create a production order without BOM & routing. Change the Config in OPL8 (order type dependent parameters) as routing optional. But it may ask for a sales order when we try to create order using CO01
2. What is the difference between PP and PP-PI? Which one is better and how ?
PP–> Production Planning mostly used for discrete type of industries, where at the time of confirmation the output is sure to be fixed. eg Automobile
PP- PI–> Production Planning for Process Industries , here mostly used for the typical chemical industries , as the Yield is not fixed due to chemical reaction yield values can be varied to noticeable extent. Eg X+Y =Z some 10 kg of X and 1 KG of Y gives yield that is Z of 10 Kg only.
3. If there are some errors in goods movements, and less stock of material consumed, how can i solve that problem in SAP ?
According to me COGI is basically a SAP standardized system which will tell you that what is the error in some cases it can rectify it too. But if the entry is done manually by MB1A, MB1B, MB1C you have to bring back or cancel the movement or move the stock to desired material and then refresh COGI.
If there are some errors in goods movements, and less stock of material consumed, how can we solve that problem in SAP ?
First you have to do revoke Teco and then process the order, otherwise system won’t allow..
4. Explain why their is need of production version ?
In production version, we assign the BOM and ROUTING combination. And in case of alternate BOMs , it clears which alternative bom has to be selected automatically.
5. What are the customer activities followed for PP module ?
PP – Discrete Manufacturing. Production Planning / Master data: For Production planning, only master data shall be migrated to SAP. In the 1st Stage, there is no master data. Following is the master data elements relevant for PP: – Bill of materials – Routing. – Work Centres.
Transaction data: As of the cut off date, ideally there should not be any work in process. All the open production orders should be closed and semi finished goods should be dismantled and should be added to Raw materials. This strategy should be followed for all production orders where lead time to complete the production order is not large. Since, the production orders are for longer duration and it is not possible to dismantle the product and add it to inventory, following can be the strategy for migrating the data to SAP:
– Create a material master for the work in process and set the standard price as the cost incurred for that product (ie. Work in process)
– Create a bill of material (which will be used only for this production order) including this material and other materials still to be consumed.
– Create Routing for rest of the production process. – Bring the work in process material into inventory as of the cut off date. – Create the production orders in SAP for the Work in process and issue materials to production order. Complete the production process after the cut off date of the project.
6. What happens to planned after it has been converted into production order ?
When you convert Planned order to Production order. the planned order are offset by production order. Reference of planned order can be seen in the production order.
7. How to attach a drawing for a material to BOM ? Is it possible ?
Yes, you can attach a drawing. First create a document using Transaction Code “CV01N – Create Document”. Attach your drawing in that document. The system will generate a document number. Assign this document in the BOM with item category D. Report in Long Term Planning – You use long term planning for your customers, what they need are very simple, just to calculate future requirements for 1 or 2 years.
8. Are there any reports in SAP to list of material requirement from LTP ?
You need a list of material requirement from long term planning result for each item. Use MS70 then use MCEC.
9. Scheduling planned order – How can you get planned orders scheduled so that you can do capacity leveling ?
MD11 and then Schedule works fine but ideally you would want the planned order scheduled automatically on creation? You have tried setting up an action to schedule the orders but cannot get that to work either. When running MRP, try selecting “2” in the scheduling box this will bring planned orders into CM01 and CM21 Capacity planning CM01 – When you run capacity planning T-code: CM01, you found the plan orders are not included in the pegged requirement, you checked the profile, the check box for order and plan order are all active.
Guess that planned orders have been created without capacity requirement indicator in MRP (“2” – Lead Time scheduling), if this is the case, then when converted to process orders they will have impact on the Resource. If you want to see them as planned orders, re-run the MRP or change in every planned order, going to the Menu: Edit –> Scheduling Another couple of possibilities are to do with the routing/work centers used and whether it is actually calculates consumption of capacity of the category at the work centre being displayed in CM01 (it might consume a capacity pool or it might not consume the category).
MPS in Background/Online – You want to run MPS for a plant either online or in the background, but you do not get any results. If you run MPS for a single material/plant, then everything is 100% OK. You need to run a planning file and a consistency check first, transaction OMDO and MDRE respectively you’ll need to set up two jobs to do it but it is straight forward, once you’ve done this set up the background job for MPS to run and do it in NEUPL first time round and then change to NETCH after that.
10. What is the output of MPS run ?
From MPS run you plan the materials which are of ‘A’ type in the abs analysis (80% dollar value) that have to be planned before hand. MPS is also a type of MRP only in which components just below the materials on which MPS run is taken place, are planned. Table for production order status – What is the table for finding status (for Ex TECO end prod orders). We are not able to find from AFKO and AFRU tables the status of production orders or at least the link tables if known can be mentioned.
You are unable to link the structure cuffed and IOHEADER WITH AFKO and AFRU. JEST is the table. Data dictionary table for SOP planning data – You are using Standard SOP (Info structure S076), in which table can you see the planning values that you maintained in MC93 transaction? You looked under table “S076” and did not see any values there.
Use Tcode MC95 to display your entries under the version which maintained the table S076. Production order operation’s component allocation – How does SAP know that an operation has components as indicated by the component allocation indicator? Tcode CO08. Component allocation is done via routing maintenance or BOM maintenance for the assembly. This is master data maintenance. As soon as a PO is created, the master data is read into the PO.
11. How to delete a group of products that was created in screen MC84 ?
Delete the members in the product group and then archive the product group in transaction SARA, object=MM_MATNR. (The product group is created as a material master record with material type PROD and this record is deleted in SARA.)
12. Explain how the PP Module is Organized in SAP.
The PP module is made up of the following components:
PP-BD Basic Data
PP-SOP Sales and Operations Planning
PP-MP Master Planning
PP-CRP Capacity (Requirements) Planning
PP-MRP Material Requirements Planning
PP-SFC Production Orders
PP-KAN Kanban
PP-REM Repetitive Manufacturing
PP-PI Production Planning for Process Industries
PP-PDS Plant Data Collection
PP-IS Information Systems
13. Explain How ‘PP’ is ‘Integrated’ with Other Modules.
‘PP’ is one of the modules in SAP R/3 that is complex as the functions cut across many modules.
The following modules are tightly integrated with PP:
CO Controlling
FI Financial Accounting
MM Materials Management
SD Sales & Distribution
PS Project Systems
PD Personnel Planning and Development
14. What is a ‘Work Center’ in PP?
A ‘Work Center’ in PP (PP-BD-BOM) is an organizational unit that can be a combination of machines or groups of craftsmen, people, and production lines, wherein certain operations are carried out to produce some output. Each of the work centers is assigned to a cost center. A work center can be assigned to a work center in SAP-HR, which will enable assignment of employees, qualifications, etc.
15. What is a ‘Routing’ in PP?
A ‘Routing’ in PP (PP-BD-RTG) is used to define the sequence of operations (work steps) and resources required to perform certain operations in order to produce a material with or without reference to an order. The standard values of planned time for the various operations need to be entered into the routing.
There are two different types of routing:
Routing
Rate routing
(A similar concept exists in PS where you define a ‘task list,’ which is similar to ‘routing’ in PP.)
16. What is a ‘BOM’?
A ‘BOM (Bill of Material)’ is nothing but a structured list of components (with the object number, quantity, and unit of measure) that go into the making of a product or an assembly. Depending on the industry sector, they may also be called recipes or lists of ingredients. The structure of the product determines whether the bill of material is simple or very complex.
17. What are the ‘BOM Categories’ Supported by SAP?
The following are the various Categories of BOM:
Equipment BOM
Material BOM
Sales Order BOM
Document Structure
Functional Location BOM
WBS BOM
18. What are all the ‘Technical Types of BOM’?
There are two ‘Technical Types of BOM’ supported in SAP:
Variant BOM
Material BOM
19. Differentiate ‘Variant BOM’ from ‘Multiple BOM.’
While a ‘Variant BOM’ groups together several BOMs that describe different objects (for example, different models of a car) with a high proportion of identical parts, a Multiple BOM groups together several BOMs that describe one object (for example, a product) with different combinations of materials for different processing methods.
The Variant BOMs are supported for the following BOM categories:
Material BOMs
Document structures
Equipment BOMs
Functional location BOMs
Multiple BOMs are only supported for Material BOMs.
20. Define ‘BOM Group.’
A ‘BOM Group’ is a collection of BOMs that lets you describe a product or a number of similar products. The value in the BOM group field uniquely identifies the BOM group. You can use the BOM group as an alternative way of accessing the BOM. A BOM group comprises either all the alternatives of a multiple BOM or all the variants of a variant BOM.
When you create a BOM group, the system checks the special characters you use. Apart from the usual alphanumeric characters, you can use the following special characters: ‘-’,‘/’,‘_.’ You cannot use blanks.
