Sources of supply ( CONTRACT) not visble in SNP

we plan to use contracts as source of supply , we created some contracts in ECC and CIF successfully to APO system , although they are visible in APO side in external procurement relationship , they are not visible during interactive mode on the SNP planning book with Distribution receipts.

we also notices that source of supply ( contract) it is visible from /SAPAPO/RRP3 while creating order.

can anyone please let us know if they have similar behaviour for Contracts

we are currently on SCM 701
