• Dynamic Internal Table Subramanian Venkateswaran Company: L&T Infotech Nov. 19, 2004 11: 45 PM Permalink On searching the ABAP forums, I did find many queries (in fact, there were a few queries last week as well) to create a dynamic internal table. I have identified a couple of scenarios and methods by which we can create a dynamic internal table. Tools Required Knowledge on data references, field-symbols is an added advantage, as they are extensively used in all the approaches. Create a Dynamic Internal Table Scenario 1 ------------------Assuming, in an internal table, you have entries of field names, which should be present as columns of a dynamic internal table. For e. g. we have an internal table, LT_INTERNALTABLE. Entries in LT_INTERNALTABLE are: FIELDNAME MANDT CARRID CONNID FLDATE PRICE CURRENCY To be converted to MANDT CARRID CONNID FLDATE PRICE CURRENCY 100 LH 0400 28. 02. 1995 899 DEM 100 LH 0454 17. 11. 1995 1499 DEM Data Definition *** Tables DATA: LT_DATA type ref to DATA: LT_FIELDCATALOG type LVC_T_FCAT. *** Structure DATA: LS_FIELDCATALOG type LVC_S_FCAT. *** Data References DATA: NEW_LINE type ref to data. *** Field Symbols FIELD-SYMBOLS: <FS_DATA> type ref to DATA, <FS_1> type any table, <FS_2>,
