kEEP GETTING INPUT ERROR WHEN RUNNING material_unit_conversion

[Former Member]

I am tryng to run this FM in test mode and I put an amount in the Input and it says it needs to be in a numeric format, which it isn/ Does anyone know how this works. Also what value should i be putting in for MEINH and MEIN fields? Is one the UOM I want it converted to?

You cannot run function module MATERIAL_UNIT_CONVERSION in test mode (in transaction SE37). This is because the parameter INPUT, OUTPUT, UMREN and UMREZ do not have a data type assigned to them.

The only way to test this is calling this function module in a test program. Here is a sample code:

CONSTANTS: C_QUANT TYPE I VALUE 1.
DATA:  P_MATNR LIKE  MARA-MATNR,
           P_FROM_UOM like MARA-MEINS,
           W_FR_CONV_QUANT TYPE F.

  CALL FUNCTION 'MATERIAL_UNIT_CONVERSION'
       EXPORTING
            INPUT                = C_QUANT
            KZMEINH              = ' ' "Base UoM
            MATNR                = P_MATNR
            meinh                = p_from_uom  "Alternative UoM
            MEINS                = MARA-MEINS  "Base UoM
            EXTENDED_CONV        = ' '
            TYPE_UMR             = ' '
            NO_OUTPUT            = ' '
       IMPORTING
            OUTPUT               = W_FR_CONV_QUANT
       EXCEPTIONS
            CONVERSION_NOT_FOUND = 1
            INPUT_INVALID        = 2
            MATERIAL_NOT_FOUND   = 3
            MEINH_NOT_FOUND      = 4
            MEINS_MISSING        = 5
            NO_MEINH             = 6
            OUTPUT_INVALID       = 7
            OVERFLOW             = 8
