Creating legacy master data:Tcode: AS91

Question

Hi guys,
When i am trying to upload some data for AS91 tcode thru LSMW and BDC, I could not upload the data to few fields , which are NON-EDITABLE mode of a screen of AS91.
Process to go to the screen as follows.
1)Tcode AS91, provide Aseet class, company code
2)click take over values , after entering description and capitalized on field.
3)enter cost center (eg: 440500), plant (1000)
now we get a screen, where we have last column, which is not editable
how to upload the data into these non editable fields.
some consultants sugested that it may not be possible with BDC, LSMW. May be possible with BAPI.
Please help me the way to over come this issue in ABAP perspective.
Note: may be with functional configuration, we can enable the fields, but requirement is to upload the through ABAP only, without changing the functional configuration.

Answer 1

you can use smae table that is CUMULATEDVALUES
for first record the value of  lwa_postv-area = '01'.
append internal table for all possible value
for 3rd  record the value of  lwa_postv-area = '15'.
again append internal table for all possible value
for next   record the value of  lwa_postv-area = '30'.
again append internal table for all possible value
