Free block – CallBlock invoked If you want to add records if certain conditions are fulfilled, you can use a Free block. For example, you can include the accumulated sum on every tenth article line, even if the sum is not included in the input data. To be able to do this, you must add a Free block with a record that includes a variable for the sum. Then create a script after the article block in which you calculate the accumulated sum and assign it to the variable. In the script, you must also count the article lines to be able to call the Free block from every tenth line. This block can be invoked using the CallBlock scripting function. See the Scripting reference. To add the block In the Process view, right-click the Free blocks folder and select Insert Free Block. The new free block is added to the Free blocks folder.
