How To Fix EL256 - Device &1: MR documents exist after activity date. Activity denied

SAP Error Message - Details

• Message type: E = Error

• Message class: EL - IS-U meter reading data processing

• Message number: 256

• Message text: Device &1: MR documents exist after activity date. Activity denied

What causes this issue?

Meter reading documents exist after the transaction date.

Additional information: When changing the logical register allocation,
or adding/removing a register (if at all, then through the "No meter
reading" indicator), these future meter reading orders cannot be
automatically updated to the modified status. This is only possible for
small modifications (such as number of decimal places, unit of
measurement, and so on).
ELSE
Additional information: A move-in already exists at the installation on
the day of the device replacement. This means that the meter reading
orders have different meter reading reasons to reason 06 (move-in). This
constellation cannot be recognized.
ELSE
Additional information: (At least) one register with a time variable
control group is involved. An automatic adjustment of these future meter
reading orders is not possible.
ELSE
Additional information: (At least) one of the later meter reading orders
is to be interpolated. This is not possible in this context.
ELSE
Additional information: The reassignment of these meter reading
documents to the new device ended with an internal error. One of the
reasons for this could be that the new device does not yet exist in the
database and must be created as a device info record.
ENDIF

System Response

Transaction execution is rejected.

How to fix this error?

You must use the reversal function to delete those meter reading
documents that lie after the transaction date from the meter reading.

• What is the cause and solution for SAP error message EL256 - Device &1: MR documents exist after activity date. Activity denied ?

  The SAP error message EL256 indicates that there are Material Requirements (MR) documents that exist after the specified activity date for a device, and as a result, the activity is denied. This typically occurs in the context of maintenance planning and execution within SAP PM (Plant Maintenance) or similar modules.
  Cause:
  
  MR Documents Exist: The primary cause of this error is that there are outstanding Material Requirements documents (such as purchase requisitions or reservations) that are linked to the device or equipment in question, and these documents have dates that extend beyond the activity date you are trying to process.
  Activity Date: The activity date you are trying to use for maintenance or other operations is set to a date that is earlier than the dates of the MR documents.
  System Configuration: The system may be configured to prevent activities from being executed if there are pending MR documents that could affect inventory or resource availability.
  
  Solution:
  
  Check MR Documents: Review the Material Requirements documents associated with the device. You can do this by using transaction codes like ME53N (Display Purchase Requisition) or MB23 (Display Reservation) to identify any outstanding documents.
  Adjust Activity Date: If possible, adjust the activity date to a later date that does not conflict with the MR documents.
  Clear MR Documents: If the MR documents are no longer needed, consider deleting or closing them if they are not relevant to the current maintenance activity.
  Consult with Planning Team: If you are unsure about the MR documents, consult with your planning or procurement team to understand the implications of any changes you make.
  System Configuration: If this is a recurring issue, it may be worth reviewing the system configuration with your SAP Basis or functional team to see if the settings can be adjusted to better accommodate your processes.
  
  Related Information:
