Question

Can anybody please tell me in detail the following:
1)  What are the tolerance groups for in MM and what are tolerances? What is the difference between tolerances and tolerance groups?
2) What are the tolerance groups for in AP and what are tolerances? What is the difference between tolerances and tolerance groups?
Thanks

Answer 1

In IMG, FI path.
OBA4 - Define Tolerance Groups for Employees - here we specify upper limits for postings and permitted payment differnces.  Usually we leave the tolerance group field as blank as the users, by default, have a blank tolerance group assigned to them.  You can create a tolerance group with a 4-character ID in OBA4 (instead of leaving it blank) if you want two (or more) tolerance groups and then assign that tolerance group to required users in OB57.
In OBA3, you can create tolerance groups which can be assigned in customer/vendor master records.  If you want to work with uniform tolerances for all customers/vendors in a company code, create a tolerance group with the key "blank" in that company code.  In this case, it will not be necessary to enter a tolerance group in the customer/vendor master record.
In MM-LIV-Authorization Management path, you have the node "Assign User Tolerane Group" (T Code OMRC), which is same as OB57.  In the same path, there is OMRB (Define Tolerance Groups) which is same as OBA4 in the FI path.
Then there is "Configure Vendor-Specific Tolerances" (T Code OMRX) in MM-LIV-Incoming Invoice, where you define tolerance groups for each company code. You can assign these tolerance groups to each vendor in the vendor master record.
In MM-LIV-Invoice Block, use can use "Set Tolerance Limits" (OMR6) to specify the tolerance limit for each tolerance key.  These keys are SAP standard.
Tolerance is the deviation allowed in a transaction.  Tolerance group is just to group together certain users / customers / vendors for whom you want same tolerance allowed.
Assign pts it this helps!!!
