External accural & settlement process for TPM Rebate with ECC rebate settlement

Dear Gurus

We have configured Lumpsum rebate in TPM with ERP Rebate & ERP rebate settlement. We are able to generate:-

1. Rebate conditions

2. Rebate Agreement

3. Fund Usage

Now we are doing Manual accural in ECC & trying to transfer accruals back to CRM & post it in checkbook.

We are using  reports RCRM_MKTPL_TPM_EXT_ACCRUALS & then RCRM_FM_ACL_ACCRUAL_POSTING_FM.

but after runnig these reports nothing is getting updated in checkbook.

Could someone please guide us through

Regars
