Equipment Serialno data segment inconsistency

Question

We have build a custom application where we tried to automate the Equipment sales process.
Scenario : Trying to sell Equipment materials in sales order with
multiple line items using a custom development. Each line item in Sales order is associated with serial no is a unique combination with material.
Process steps as followed
1. Will create seperate delivery for each item in the Sales order.
2. Retire Assets
3. Update Material with Retirement value
4. GR done for each delivery using BAPI_GOODSMVT_CREATE using movement type 501.
5. PGI using movement type Z01.
6. Billing document generated.
In step 4, calling BAPI_GOODSMVT_CREATE to do GR by passing serial no
to GOODSMVT_SERIALNUMBER. Table EQBS gets updated, EQUI-S_EQBS is not
getting updated through bapi, if sales order has more than one item.
This is causing problem when we try to return these sales orders, getting short dumps EQUI-S_EQBS flags
are inconsistent with EQBS data.
I found an SAP note where we can correct these flags by running a report, but i would like to find a cause and prevent frombeing happening.
Appreciated your inputs.

Not sure if this is your problem...
I know when you use the AT statements in a LOOP, everything to the right of the key is "*".  You have to make a work area like the structure in your LOOP, move the data to it after the LOOP, and then reference ths structure within the AT/ENDAT statement.
like...
data: w_idoc_sdata like idoc_data-sdata.
loop at idoc_data.
  w_idoc_sdata = idoc_data-sdata.
  at last.
    MOVE w_idoc_sdata TO w_e1edl43.
  endat.
