Incoming and outgoing IDocs are usually linked to other relevant documents, so that you can easily identify all documents for a process if an error occurs. If you do not need these links in some cases, you can deactivate them. This minimizes the amount of data saved in the IDoc processing.
· You can deactivate the following types of link:
IDC0 |
Outgoing document linked to outgoing IDoc |
IDC1 |
Incoming IDoc linked to incoming document |
IDC2 |
Incoming IDoc linked to Communication IDoc |
IDC3 |
Incoming IDoc linked to Original IDoc after editing |
IDC4 |
Incoming IDoc linked to outgoing IDoc in source system |
IDC7 |
Outgoing IDoc linked to Original IDoc after editing |
IDCB |
Incoming IDoc linked to outgoing document in source system |
IDC9 |
Outgoing IDoc linked to incoming document in the target system |
· You can deactivate the writing of link types for all message types, or only for selected message types.
· You can not deactivate links if you need them later to reconstruct a document flow. If, for example, you want perform an ALE Audit for a message type, you cannot deactivate the link (link type IDC4) for this message type.
· You cannot deactivate links below the message type level. For example, you cannot deactivate a link for the message type ORDERS only for some sender systems. You can only deactivate this link for all IDocs of message type ORDERS.
Deactivating links can be useful in the following cases:
· IDocs from external systems without IDoc management
If the sending system has no IDoc management, the number assignment to outgoing IDocs of this system is ambiguous. Links to the incoming IDoc would therefore be meaningless.
· Bulk processing of master data
If an error occurs during bulk processing of master data, the entire process, not individual IDocs with errors, is repeated. You do not need to link individual IDocs in this case.
Choose SAP menu ® Tools ® IDoc Interface/ALE ® Administration ® Runtime Settings ® Deactivate Links (transaction code WENOLINKS).
1. If you want to completely exclude a link type, select the type under Not Excluded Link Types, and choose Move Link Types.
2. If you want to no longer exclude a link type, select the type under Excluded Link Types, and choose Move Link Types.
3. If you want exclude a link type only for some message types, select the type and choose Exclude Message Type. Enter the name of the message type in the following dialog box. Repeat this procedure for all message types for which you want to exclude the link type.
4. To reverse step 3, select the message type and choose No Longer Exclude Message Type.
