Not able to transfer Contract Data from SRM to PI

Dear Experts,

We are not able to transfer Product Category for contract data from SRM to MDM catalog through PI.

SRM version: SRM 7.0

version :SRM-MDM CATALOG 7.02

we are using  Program SRMMDM_CTR_TRANSFER for contract transfer.

Our problem is contract has line items and product category but that data is not in the payload which we sent to PI

Please let me know urgently if any note we have to apply in SRM/PI to send product category from SRM to PI

Thanks

Vaibhav
