Having issues with initial data load in MDG BP

Hello Experts,

I have followed below steps to do initial data load in MDG for BP but unable to complete data load.

1. Created change request using " USMD_CREQUEST_CREATE" for
   "Business Partner ID" Entity Type
2. Started data load process using " USMD_FILE_LOAD" and then
   choose "Business Partner ID" for Entity Type and selected Data row
   exactly I have in my text file
3. I get an error message saying "NO Change Request is assigned to you
4. I went to look at change request work flow and I don't see any Change
   request working for my approval and when I select change request which I
   created in step 1 it tells me that I am not the processor of this change
   request
5. I did verify assign processors by going to MDGIMG> General
   Settings> Process Modeling> Workflow> Other MDG Workflow> Assign
   Processor to change request step number

I don't know what I am missing which doesn't recognize my change request
thru File upload process. Would appreciate any help you can provide.

Thanks,

Meghna
