The system does not get Storage Location of the material from the Contract

Question

Hi to all,
We are encountering a problem now regarding the PR to PO conversion.  Our ABAPer has made a background job for the User to convert a PR to PO using ME59N. 
Background Job : ZPTI_MM_PR_PO_CON
Program : RM06BB30
Tcode: ME59N
Variant : SAMPLE2_ME59N ( Plant, Vendor, POrg, Pgrp.)
Rule : When the PO is converted the STORAGE LOCATION of the material should be gotten from a CONTRACT/AGREEMENT instead of the SLoc defaulted in PR.
Problem:  When the backround job is finished, the PO is converted but the STORAGE LOCATION did not get from the CONTRACT.
Steps done :
1. Create a Contract (ME31K)
    1.1 Specify the SLOC of the material
2. Create PR (ME51N) and enter the Contract Number inside the PR
    note : In the PR the material has a Storage Location which defaults from the Material Master.
3. Run SM36 and enter the job ZPTI_MM_PR_PO_CON
4.  Set the job to "Immediately"
5. Click Steps icon and enter the program RM06BB30 and variant SAMPLE2_ME59N
6. Save
7. Go to SM37 and check the job if finished.
8. When the job is finished, check the PR if it has a PO.
9. Display the PO.
10. Check if the storage location in PO has gotten from the Contract
     The problem now appeared.
We have tried to use ME59N alone and not using the background job. The system has gotten the correct Storage Location, thus it got from the Contract.
Please help what should be checked on our side.  Our ABaper is also currently debugging the program but we
are seeking help to fasten the solution.
Best Regards,
Elynne

Hi Elynne,
Definitively, it is a problem with ME59N background process.
It is better if you can create a message to SAP asking for the solution.
I only found the next SAP note:
Note 1287723 - ME59N in backgound does not populate PR details in PO.
But, I do not know if it will help to resolve your issue.
I hope this little information can help you in anyway.
Kind regards,
Sandra
