Hi,
I agree with Alan - but the storage location field doesnt exists in the standard condition structures KOMG / KOMP. So you can not directly add the storage location field in the condition field catalogue and in the condition tables.
If required, you may maintain the field in the structures by appending the structure. Refer the note: 566002 - M/03: Can't use field PSTYP in the condition table
Once the field is added to the structure, you may add the field from the field catalogue and then create the condition table with storage location.
Now, check the access sequence assigned to the base price condition type in M/06. Go to M/07 and maintain the new condition table with a step number (say step num 1) less than the step number of the info record table 017. Now, maintain the condition record in MEK1. Test the scenario with a new PO.
