EXPORTING

bind_texts = 'CN_RULEBUILDER.CA_CONDITION'

RECEIVING

control = lr_input ).

lr_group ?= view->get_element( 'GRP_BUILDER' ).

lr_group->add_child( lr_input ).

when i run this i get dump

Adapter error in MATRIX_LAYOUT "_03" of view "ZMCPTS_RULES_SCREEN.V_MAIN": No LayoutData exists for child element "_10" of the UIElementContainer

Can someone please help me with this

This is because you need to set the Layout for the new element added as below:

data LR_FLOW_DATA type ref to CL_WD_FLOW_DATA.

LR_FLOW_DATA = CL_WD_FLOW_DATA=>NEW_FLOW_DATA( element = lr_input ).

Thanks,
