Values are cleared on Activation of customer in MDG-C

Hi Gaints,

I am creating a Customer in MDG-C from custom program using Change request API interface 'IF_USMD_CREQUEST_API'.

All values are passing to proper fields but I am facing an issue like on activation some values are cleared and same is not updating in database tables.

Customer is creating in database but values from sales area, marketing and Additional data block is getting cleared.

Is anyone come across this kind of issue or can anyone suggest some solution for this.

Screenshot as below;

1. Customer below Activation

2. Customer after Activation.
