pdf distribution failed ..?

[dhasharadh]

distribution failed due to the below error, we are using the loop and reduce option and we are bit new to this type of requirement.

we have an app called A which is used to trigger and generate pdf files using loop and reduce. 

we tried triggering the same app but its not working, so we thought that it was corrupted and created a new task by taking the copy of the app. but facing the below error. no idea and when we tried to see the script its not visible, this is bit tricky..

 @marcus_sommer @Miguel_Angel_Baeyens @Bill_Britt can any one you please  guide us. Thanks Much in advance.

Hi, I don't know but doing a search throguh community possible causes can be:

-lack of space: https://community.qlik.com/t5/QlikView-Publisher/Publisher-not-sending-PDF/td-p/626531

- pdf printer corrupted or with short timeout: https://community.qlik.com/t5/New-to-QlikView/Failed-to-generate-QVW-File-package/td-p/723099

Thanks RubenMarin, 

a week back also it generated pdf files, there is less chances for pdf printer corruption. How can i know that it is because of the PDF printer issue.

Hi, sorry but I don't know, haven't found this issue by myself, I just did a search for "qlik publisher No Document Package found".

There is another one solved with help of @ashfaq_haseeb:

[marcus_sommer · Accepted solution]

Maybe the cause is exactly what the error-message said: "... Field does not exist. Loop not possible. FieldName: System ...". Therefore take a look within document-log if this part of the tasks is finished successfully and if the field is included or not. Further check if any section access omit this field and/or that the field has real values and isn't only NULL - from the point of view for the executing user.

Just including Help Doc links for Reduction and Distribution using looping feature:

https://help.qlik.com/en-US/qlikview/April2020/Subsystems/QMC/Content/QV_QMC/QMC_Documents_SourceDoc...

https://help.qlik.com/en-US/qlikview/April2020/Subsystems/QMC/Content/QV_QMC/QMC_Documents_SourceDoc...

Generally using Loop and Reduce will require Loop and Distribute as well given most use cases are wanting to restrict access to the reduced apps to just certain groups of users in those cases.
