Process Control workflow - want to delete logical steps against one SC

Question

Workflow issue : Process control workflow
In my scenario when requestor is creating a SC then workflow goes to buyer for assignment of supplier but when buyer himslef is creating a SC and forgot to attach supplier then workflow goes to error....i checked in SWIA its an error.....
i come to know tht we can logically deleted those steps , so that when buyer open a SC in edit mode and assign Supplier then workflow will behave as normal.
Please let me know where i can logically deleted the steps for particular work item ID.

Hi ,
  Yes - what Masa suggested is the correct and the SAP Best Practice, I'll do the same. you can implement the BAID BBP_DOC_CHECK_BADI , where you check whether the requester is Buyer or not, if the requester is buyer , you can get the assigned role from BUS4101 by passing the user id or calling the FM 'BAPI_USER_GET_DETAIL'. if the  'ACTIVITYGROUPS'
table from FM ''BAPI_USER_GET_DETAIL' has an entry 'SAP_EC_BBP_PURCHASER' then the requester is a buyer. you can write your logic after that to make sure the SC has assigned supplier or not. if the SC is not assign the supplier then raise the error message.
