Remove attachment

The action used to delete attachments from workflow instances.

Remove attachment

1. Category​

Attachments to be processed will be selected based on their category.
Define it by selecting one of the following options:

  • All – attachments belonging to all categories will be selected,
  • Dynamic – create the category dynamically (using Variables editor) or enter it manually. The category can be provided in BPS format (i.e. ID#Name) or as ID.
  • No category – attachments not belonging to any category will be selected.

Additionally, specify which attachments from the chosen category should be selected: All attachments, only The oldest attachment or only The newest attachment.

2. Regular expression​

Attachments to be processed will be selected based on a regular expression.
Use the Regex Creator as an aid in constructing the expression.

3. SQL query​

Attachments to be processed will be selected based on an SQL query.
This query should return a list of attachment IDs from the "WFDataAttachments" table.

4. Advanced configuration​

With the Advanced configuration, you can indicate Deletion mode for attachments of the workflow instance:

  • Remove attachment and leave attachment’s history – the attachment is deleted from the workflow instance, but the historical data are retained in the database,
  • Remove attachment and all binary data – the attachment is deleted from the workflow instance, and the historical data are also deleted from the database,
  • Remove only history of binary data – the attachment remains on the workflow instance, but historical data are deleted from the database.

5. Variables editor​

Dynamically generated tree containing all variables that may be used in the current location of Designer Studio. Information on how to use variables in WEBCON BPS, as well as a list of variables can be found here.
