How To Fix 37564 - Only one of two elements & is in the loop (cannot be tranformed)


37564 - Overview

  • Message type: E = Error

  • Message class: 37 - Screen Painter

  • Message number: 564

  • Message text: Only one of two elements & is in the loop (cannot be tranformed)

  • Show details Hide details
  • In the selected area, which is part of a loop block, you attempted to
    convert screen fields to checkboxes or radio buttons.
    Two screen elements exist for the specified field name - a template
    (input/output field) and a field text. Of these, one lies inside the
    loop block and the other outside.

    System Response

    The conversion was rejected because the field text with a button as
    graphical element must form a unit and a graphical unit cannot lie
    partly inside and partly outside a loop.

    How to fix this error?

    First, give the template or the field text a different name.
    If you want to use the text field as a template header (i.e. as a
    textual explanation for the intended checkbox or radio button), you
    should prefix the name of the field text with an asterisk ('*').
    Fields with names where the only difference is an asterisk as prefix
    are treated the same at runtime for the F1 help. This means that, when
    you define F1 documentation for the data element, it becomes effective
    for the header.
