No Source of Supply / PDS seen in SNP against Production order CIFd from ECC

Dears,

In the 'display details' of key figure 'Production Confirmed' I was hoping to see the Source of Supply/PDS used in ECC to create this process order directly. It was not converted from any planned order created in either system. The process order was created in ECC with reference to a Production version in ECC. This PDS against this Production Version exists in APO by virtue of CIF done before.

Why don't I see the PDS used against the production order above in APO? or should I? I do not see the PDS either in SNP data view or in the RRP3 view

Note: this is an SNP PDS. Not PPDS PDS exists.

Thanks

Amit
