MRP + Batch determination/restriction complex sceanario

Question

I have a very complex issue with MRP and Batch Determination. Here is my
situation. Please help me find a solution.
I have materials which are batch managed and each material can have numerous batches based on the quality (80%, 70%, 90%). Materials can have up to 100-150 batches. Some batches can be used only by some customers (Plants, Customers) in different countries because of legal issues. When
we run an MRP, MRP doesn't care which batch it is, it just creates planned orders/purchase reqs based on the quantity, material and plant. Just to give you an example, Lets say we have material A which as 2 batches Batch 1 and Batch 2. Lets say we have customer x and Customer y. Customer X can use only Batch 1 for the material not batch 2 because of legal issues and standards. Customer y can use Batch 1 and also batch 2. When we run an MRP, MRP is suggesting to send batch 2 to customer x which is not right. Storage location creation is out of question coz of business requirement in those countries.
Is there any user exit or enhancements that i can look into, or can I accomplish this through custom z tables/tcodes ? Is there any other way I can handle this through master data change ?
Please help me out on this and let me know what other possible ways we can handle this issue.
Thanks,
Mike

Hi
I think your requirement can be mapped using standard Batch determination set up. Pl try with...
1) Create 2 more Char in CT04 like Plant and Customer and assign to the batch Class already exists (023). The idea is to give plant and customer data values to each batch along with other batch char values
2) In the SPRO > Log- gen > Batch mgt > Batch determination and Batch chk
   a) Create new condition table with Customer/Plant/Material/Mvt type
   b) Create Access table
   c) Create Strategy type
   d) Create Search Procedure and assign Stg type
   e) Assign the Search procedure to mvt type 261
3) Create Batch search strategy in MCB1 for the Strategy type created earlier for the combination
    Customer/plant/mvt type/material combination and maintain sorting rule and Batch search criteria and maintain classification data
Example of Batches say
Batch-123            Batch-231_
Density- 1                   Density- 1.2         
Viscosity - 1.8             Viscosity - 1.8
Plant - 1000                 Plant - 1100
Customer - A               Customer - A
4) Now while running MRP system will pick up the Batches corresponding to that plant or customer. Hope this will solve u r problem. Pl revert back for more info
