XC240 - Overview

• Message type: E = Error

• Message class: XC - Message Class for Core Interface

• Message number: 240

• Message text: Function module &1 does not exist in remote system &2

What causes this issue?

Usage check for location corresponding to selected customer/vendor
should be performed in SCM system. Called function module &V1& doesn't
exist in the called SCM system &V2&.

System Response

If function module /SCMB/LOC_EOP_CHECK used for EoP check of locations
corresponding to selected customer/vendor doesn't exist in SCM system,
warning is displayed. In such a case, the system attempts to call
function module /SAPAPO/SCMB_WUC_LOCATIONS to perform where-used check
for the locations in SCM system. If also this function module doesn't
exist in SCM system, another warning message is displayed and no check
is performed.

How to fix this error?

If none of the two function modules exist in the called SCM system &V2&,
contact your system administrator.
In this case it might happen that customer/vendor is blocked in ERP,
although the corresponding location exists in SCM system &V2&.

Procedure for System Administrators

Implement SAP Note 2226353 in your SCM system. This creates function
module /SAPAPO/SCMB_WUC_LOCATIONS in the SCM system and prevents
inconsistencies between ERP and SCM system.
