Creation of Dynamic Action

Dear All,

I have to write a Dynamic Action (v_T588z) for my customize infotype. In that infotype, i have to set a condition on fields, that if Installment amount is less than the balance amount than the system should create wage type in infotype 0014 against Balance amount. And also create a period dates (Start and end date) in that subsequent period against the creation of wage type in infotype 0014.

Please note that the Dynamic Action for wage type creation and updation is already written against installment field per month.

You are requested to kindly write me a code for Dynamic Action for the above mentioned requirements.

Thanks & Regards,

Hassan
