2581230 - Error Source Of Suppy For Purchase Proposal XXX Not Valid While Creating New Planning Proposal


You are creating a New Planning Proposal for the Product ABC (ABC represents the Product ID) but you receive the following error message: Source Of Suppy For Purchase Proposal XXX Not Valid (XXX represents the Purchase Proposal ID).


SAP Business ByDesign.

Reproducing the Issue

1. Go to Work Center Supply Planning.

2. Open View Products.

3. Find Product ABC and Open it.

4. Under Supply and Demand List click the New Planning Proposal button.

5. Specify the Quantity and press Enter key on your keyboard.

Result: An error Source Of Suppy For Purchase Proposal XXX Not Valid will be displayed.


The cause will be explained by the following example:
As Source of Supply for Product ABC you are using List Price. You have updated the List Price with a new one which is Released and valid and you are expecting this List Price to be picked for Planning Proposals.
For product ABC you have maintained Supplier Lead Time as 5 days. It is like in Purchase Proposal you have given Availability Date as today and to fulfill this demand the system picks the valid Source of
Supply deducting 5 days from today's date. Whatever is valid Source of Supply on that day considering Lead Times is shown as Source of Supply.  Because on the given time (in this example 5 days ago) the new List Price was still not valid, the system will show an error that the Source of Supply is not valid.


To resolve the issue you should modify either the Supply Lead Time or the Availability date, in order for the system to be able to pick a Source of Supply that is valid for the given date.
