Hi Gurus,
Need some expertise from you on one SNC issue.
I have planned production saved for 2 of the plants 3416 & 3417 in the planning book (as shown below):

I am trying to publish demand to SNC through /SAPAPO/APO_SNC_EXTRACTION for both plants 3416 & 3417:

But I am getting "Error during supplier determination for location &1 product &2" in the log:

Do you know what could have led to this error? What is missing as far as master data is concerned?
Please help me with your expert comments on it.
Thanks & Regards,
Ujwal Arora
