Shopping cart not returning to SoCo even after PO and confirmation deleted

Shopping cart not returning to SoCo even after PO and confirmation are deleted.

Steps followed:

Created shopping cart

SC approved

Assigned vendor in sourcing and created PO(PO created successfully created in ECC)

Confirmation created

Deleted the conformation

Deleted the PO

When PO is deleted SC should return to Sourcing Cockpit, but it is not returning.

Checked the table BBP_PDIGP, source_del_ind is space.

Ran BBP_GET_STATUS_2 and CLEAN_REQREQ_UP both the programs manually but in vein.
