Leading zeros for FM F4_GET_RESULT - wildcard problem

Question

Hi,
I have the following problem:
FM F4_GET_RESULT supports the search help in a BSP application.
It works fine when there is no wildcards used. However when there is a wildcard it doesn't work.
For example in case of cost centers, we use search help M_KOSTN, which based on table CSKS. There is one cost center 0002160221, which is found if I use form '000216*', however not found if I use without leading zeros.
Actually it's the same if I use SE16 on table CSKS.
I cannot really use ALPHA conversion here as I don't know how many leading zeros I have to add.
Any idea how to solve this issue?
Thanks in advance,
Peter

Hi peter,
To remove leading zeros and leading blanks
Please use FM
CONVERSION_EXIT_ALPHA_INPUT Conversion exit ALPHA, external->internal
CONVERSION_EXIT_ALPHA_OUTPUT Conversion exit ALPHA, internal->external
These function modules convert the value of an external represntation of a field into an internal format or vice versa.(Meaning for some fields like MATNR, then value which you see is not the way it is stored in the database. The value that you see is the external format, and the value which is stored inside the database id the internal format. These function modules convert the values of such fields from internal to external and vice versa.
CONVERSION_EXIT_ALPHA_INPUT This function module is used to append leading zeroes...
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
            EXPORTING
              input  = wf_version
            IMPORTING
              output = wf_version.
Example:
input = 123
output = 0000000000000...000000000000123
Hope this resolves your query.
Reward all the helpful answers.
