we are using RAALTD01 to bring in legacy asset data and are having a problem with loading the legacy asset number. I am trying to map it to field OLDn1 but this is not working. i also tried to map to txa50 with no success. I saw on the forum about a field ANLA-AIBN1. I s this the file that I have to use. I am including a sample of my mappings
mandt like t001-mandt,
bukrs like t001-bukrs, " Company code
anlkl like baltd-anlkl, " Asset Class
oldn1 like baltd-oldn1, " Old main asset number
oldn1 like anla-aibn1, " Old main asset number
oldn2 like baltd-oldn2, " Old asset subnumber
tcode like baltd-tcode, " Transaction code
RCTYP like baltd-RCTYP, " Record type for legacy data transfer
thank you in advance for the help
