SAP ABAP Problems & Solution

 In SAP sometime we need to convert string as first letter in capital format and then start with small letter word wise. For that case we need to use Function module. In my profession i did so many times. Give here example, hope it will help you to solve the issues. FM: 'FI_CONVERT_FIRSTCHARS_TOUPPER'     Data :  string   type  char255 ,       OUT_STR  TYPE  CHAR255 . string  =  ' SMALL CHANGE' .

 Need to execute transaction the Go to Settings  -> Layout -> Manages then select the line and press delete symbol.

 In SAP we use SHIFT keyword to delete leading zero's. Keyword is: SHIFT Variable LEFT DELETING LEADING '0'.  SHIFT Variable RIGHT DELETING LEADING '0'. We can also delete & add these zero's using new ABAP syntax. FM:  'CONVERSION_EXIT_ALPHA_OUTPUT' 'CONVERSION_EXIT_ALPHA_INPUT' DATA int_val TYPE char10 VALUE '0000012345' . DATA Chng_val TYPE char10.
