KB13016: Users cannot import as many attribute elements into a filter from a file as exported in MicroStrategy Developer 9.4.1, 10.x., and 2019

SYMPTOM:
After exporting a file to a text file and then importing attribute elements from the text file into a filter, the file becomes truncated in Strategy Developer 9.4.1, 10.x., and 2019.
 
STEPS TO REPRODUCE:
Follow the steps below to reproduce this issue using the Strategy Tutorial project:

• Create a report with the attribute Customer in the template. Make sure to show the ID form in the available attribute forms selection, as shown below:
  

• Execute this report and export it to a text file, as shown below. Notice that this export executes successfully.
  

• In the same report, add a filter qualification on Customer, qualify on ID, and select the qualification to be In list.
• Push the import button and select the file created from the export, as shown below:
  

• When importing this file, notice that the values have been truncated, as shown below:
  

CAUSE:
There is a limit in this List box that is 65,535 characters long. This is functioning as designed.
 
WORKAROUND:
Filter by the attribute form values that hold the least amount of character space. Numbered ID forms are ideal to maximize the list of values held in this box.
