Hi Cholen,
I believe your lv_laufd is a 10 character field in format MM/DD/YYY or DD/MM/YYYY. You should move that data to a 8 character variable (say lv_date) in YYYYDDMM format.
Please try this conversion
CALL FUNCTION 'CONVERT_DATE_TO_INTERNAL'
EXPORTING
date_external = lv_laufd
IMPORTING
date_internal = lv_date
EXCEPTIONS
date_external_is_invalid = 1
OTHERS = 2.
Check in debug, you should get lv_date in YYYYMMDD.
If you still do not get data after lv_date eq YYYYMMDD, check your LIFNR and KUNNR. They should be 10 charaters with leading zeroes if not 10 .
If needed use the conversion for lv_lifnr and lv_kunnr.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
EXPORTING
date_external = lv_lifnr
IMPORTING
date_internal = lv_lifnr.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
EXPORTING
date_external = lv_kunnr
IMPORTING
date_internal = lv_kunnr.
Cheers,
Raju.
