Basically I was adding 2 fields to the form view: Material to replace and Replacement material, then I would give the option to select multiple BOMs and each of them will replace the material selected with the replacement material. My problem was when I tried adding the code, It gives me forbidden opcode(s) error.

Im using odoo studio btw.

This is the code:

from odoo.exceptions import UserError

# Get the material to replace and the replacement material from the FIRST selected record

if records:

    first_record = records[0]

    material_to_replace = first_record.x_studio_material_to_replace_1

    replacement_material = first_record.x_studio_replacement_material_1

    if not material_to_replace or not replacement_material:

        raise UserError("Please specify both 'Material to Replace' and 'Replacement Material' in the first selected BOM.")

    # Loop through the selected BOMs

    for bom in records:

        # Loop through the BOM lines

        for line in bom.bom_line_ids:

            # Check if the material matches the one to replace

            if line.product_id == material_to_replace:

                # Replace the material

                line.product_id = replacement_material

                line.product_qty = line.product_qty #This line is added to force the recomputation of values

else:

    raise UserError("No BOMs selected.")

And this is the error:  forbidden opcode(s) in 'from odoo.exceptions import UserError\n\n# Get the material to replace and the replacement material from the FIRST selected record\nif records:\n    first_record = records[0]\n    material_to_replace = first_record.x_material_to_replace\n    replacement_material = first_record.x_replacement_material\n\n    if not material_to_replace or not replacement_material:\n        raise UserError("Please specify both \'Material to Replace\' and \'Replacement Material\' in the first selected BOM.")\n\n    # Loop through the selected BOMs\n    for bom in records:\n        # Loop through the BOM lines\n        for line in bom.bom_line_ids:\n            # Check if the material matches the one to replace\n            if line.product_id == material_to_replace:\n                # Replace the material\n                line.product_id = replacement_material\n                line.product_qty = line.product_qty #This line is added to force the recomputation of values\nelse:\n    raise UserError("No BOMs selected.")': IMPORT_NAME, IMPORT_FROM, STORE_ATTR
