Thank you for your inquiry. A short answer: choose "canonical" in the indicator box. We replaced the term formative with this one. Then, you will have only weight estimates, not loading estimates.

GSCA (and PLS) represents a construct with a component or weighted composite of indicators. These indicators forming a component are called "composite" indicators in the SEM literature. There are different types of components. One is nomological components, which aim to explain both their composite indicators and dependent components. They include component loadings for composite indicators. This is the default choice in GSCA Pro. Another type is canonical components, which aim to explain their dependent components only. They do not involve loadings, although they can be calculated afterwards as in canonical correlation analysis. In previous literature of GSCA and PLS, the indicators for nomological components were called reflective, whereas those for canonical components were called formative. 

However, I think the terms reflective and formative can apply only to the indicators for factors in factor-based SEM (often called covariance-based SEM). Thus, they are irrelevant to components. 

If you are interested in these distinctions, you may want to look at the following references:

Best,

Formative Indicator

TEGUH IMAN SANTOSO <teg...@gmail.com>: Nov 28 11:30PM -0800 Hi,   I tried to find Formative Indicator selection for the new software, but I cannot find it.   Anybody can help me if my indicator was Formative. In the previous WEB BASE I still can fid it, but I never find it on standalone software (GSCA PRO).   Best Regards,   Teguh Iman Santoso
