The default scale model class provided by SAP for communication via an RFC connection does not pass the unit of measure (UOM) to ERP-Scale. This means that ERP-Scale is unable to convert the weight received from the sale to the UOM required by SAP and can lead to incorrect data being returned to SAP.
We advise creating a custom scale model class by copying the standard class CL_CFB_SCALE_MODEL_RFC_1.
Please review SAP Note 1532217 for information regarding creating a new scale model class.
Copy the class CL_CFB_SCALE_MODEL_RFC_1 to ZPP_CL_CFB_SCALE_MODEL_RFC_1 and make the following code changes:
ENDIF. lv_unit = ls_scale-unit. *---------------------------------------------------------------------* * Send tare to scale system. *===================================================================== * Pocket Programs - ERP-Scale May 2016 *--------------------------------------------------------------------- * With a tare of Zero, no UOM is sent to ERP-Scale. This can lead to * inconsistent results as there is no check that the UOM returned * from the scale matches the UOM expected by SAP *--------------------------------------------------------------------- * Modify code to always send tare with UOM to ERP-Scale , even if * tare is zero. *===================================================================== * IF iv_tare > 0. CALL METHOD me->pack_tare EXPORTING iv_unit = lv_unit iv_tare = iv_tare IMPORTING ev_tare_packed = lv_data.

IF lv_retcode <> '0'. ev_manual_mode = abap_true. EXIT. ENDIF. * ELSE. ** Send a "clear tare" command. * CALL METHOD me->send_command( * EXPORTING * iv_funcname = lv_funcname * iv_command = gc_command-clear_tare * iv_rfc_destination = lv_rfc_destination * iv_device = lv_device * IMPORTING * ev_retcode = lv_retcode ). * * IF lv_retcode <> '0'. * ev_manual_mode = abap_true. * EXIT. * ENDIF. * ENDIF. *---------------------------------------------------------------------* * Read stable weight
