Hello Imran,
Please find response to your queries:
1. Refer the screen shot for HTML code of the mail form and the related tag for colouring.
You may be using following method to trigger e-mail.
CALL METHOD cl_crm_pml_mail_form_api=>preview
EXPORTING
is_parameters = <parameter>
IMPORTING
ev_body = <body>
EXCEPTIONS
not_possible = 1
OTHERS = 2.
<body> will give you the HTML code of the final e-mail going out to the customer. You have to write code to find the changed attribute and change its colour using the tags (refer screen shot for tags).
2. FM READ_TEXT returns multiple lines based on the data available for the document and text type. Each line is of 132 characters. If text in one order objects is more that 132 characters (including spaces and new line, carriage return). You have read the whole table output and concatenate individual lines.
Regards,
Kapil Patil
